Dear Maintainers,

The ucx package fails to build from source on ppc64el architecture due 
to a missing header include.

see build log on ppc64el: 
https://buildd.debian.org/status/fetch.php?pkg=ucx&arch=ppc64el&ver=1.21.0%7Erc2-1&stamp=1781278165&raw=0

note: each undeclared identifier is reported only once for each function 
it appears in

make[4]: *** Waiting for unfinished jobs....


Solution:
  As time.h directly uses UCS_INFINITY.
  Add #include <ucs/sys/math.h> to src/ucs/time/time.h to make it 
self-contained.

Patch:
   I have created and tested a patch that fixes this issue. The patch 
adds the missing include in src/ucs/time/time.h:

--- ucx-1.21.0~rc2.orig/src/ucs/time/time.h
+++ ucx-1.21.0~rc2/src/ucs/time/time.h
@@ -10,6 +10,7 @@

  #include <ucs/time/time_def.h>
  #include <sys/time.h>
+#include <ucs/sys/math.h>
  #include <limits.h>
  #include <math.h>


After applying this patch, the package builds successfully on ppc64el.

Please review the patch and let me know if any additional changes are 
required.


Thanks,
Trupti
